Parasitic Nutrition 21 May 2011 10:43 = organisms that live on or in another organism obtaining nourishment at the expense of the host and causing harm. Gut parasite (Taenia solium) = tapeworm Primary host = human (eat uncooked infected pork) Secondary host = pig (drainage channels contaminated by human faeces) Adaptations… - Suckers & hookers (attachment) - Body covering (immune responses) - Thick cuticle (inhibitory substances = enzymes) - Simple body systems (reproduction) - Very thin & large

Review Sheet Exercise 8 Chemical and Physical Processes of Digestion NAME Dane Wilson LAB DATE/TIME august 4th Carbohydrate Digestion The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? Why? 7.0 because that is when the salivary is most effective and it breaks down carbohydrates. 2. How do you know that the amylase did not have any contaminating maltose

types of reactions that occurred in each test tube. These reactions would be brought on by enzymes that would interact with other substances. [Part A] In this lab‚ we hypothesized that the tubes that contained a pancreatic solution would dissolve the starch‚ while the other test tubes wouldn’t. This is because the pancreatic solution contains enzymes which complete the digestion of carbohydrates‚ proteins‚ and lipids (Digestion BioKit). Although test tube three contained this solution‚ we predicted that

one disaccharide‚ is called a hydrolysis reaction and requires one water molecule to supply the Hydrogen and Oxygen-Hydrogen to the sugars formed. Some examples of disaccharides include Sucrose (glucose + fructose) which is used in many plants for transporting food reserves‚ often from the leaves to other parts of the plant‚ Lactose (glucose + galactose) which is the sugar found in the milk of mammals and Maltose (glucose + glucose) which is the first product of starch digestion and is further broken

and growth. One particularly significant enzyme is amylase‚ which catalyzes the hydrolysis of alpha glycosidic linkages of amylose‚ starch components‚ and other oligosaccharides (Qian‚ et al.‚ 1994). Porcine pancreatic alpha-amylase can be found in pancreatic secretions‚ and works most efficiently at pH 6.9 for the majority of substrates. This ideal pH‚ however‚ has shown to shift to as low as 5.2 for the hydrolysis of some

building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that can hydrolyze plant starch‚ making glucose available as a nutrient for cells. Cellulose
